Tissue expansion for correction of male pattern baldness has not gained wide acceptance by patients or surgeons because of the substantial albeit temporary deformity of the expansion. Minimal expansion is an alternative. Scalp flaps can be expanded just to the point of becoming noticeable over 4 to 6 weeks followed by scalp flap transposition and easy closure of the donor site. The temporoparietal (Juri) or superiorly based (Dardour) flaps have been used unilaterally or bilaterally. The entire restoration is completed in approximately 8 weeks, is minimally deforming during the expansion phase, and does not require the patient to alter his lifestyle significantly or to go into hiding. Hair grafts, in contrast, do not begin to grow hair until 12 weeks after transplantation, and the process usually requires four sessions over an 8- to 12-month period with the patient looking temporarily variably absurd. Tissue expansion increases scalp available for flap restorations, which appear more natural than even the most well-executed hair transplants. Minimal expansion makes the process more palatable to the patient and surgeon.
由于组织扩张虽为暂时性但会造成明显畸形，通过组织扩张来矫正男性型秃发尚未得到患者或外科医生的广泛认可。最小限度扩张是一种替代方法。头皮瓣可在4至6周内扩张至刚能被注意到的程度，随后进行头皮瓣转位，供区易于闭合。颞顶（尤里）瓣或上蒂（达杜尔）瓣已被单侧或双侧使用。整个修复过程约8周完成，在扩张阶段变形最小，且无需患者大幅改变生活方式或隐匿。相比之下，毛发移植直到移植后12周才开始生长毛发，且该过程通常需要在8至12个月内进行四次手术，在此期间患者外观会暂时显得颇为怪异。组织扩张增加了用于皮瓣修复的头皮面积，皮瓣修复后的外观比即使是最精细的毛发移植看起来也更自然。最小限度扩张使该过程对患者和外科医生来说更容易接受。
